The question asked, verbatim: best ecommerce platforms for online stores

Brands named, in the order the engine gave

1. Shopify recommended
   Shopify - the default recommendation for most people.
2. Shopify Payments mentioned
   The catch: if you use an external payment gateway instead of Shopify Payments, you pay an extra 2%, and app subscriptions can quietly exceed your plan fee as you grow.
3. WooCommerce mentioned
   WooCommerce - the pick if you're already on WordPress or your business is content-led (blog, SEO, editorial driving sales).
4. WordPress mentioned
   WooCommerce - the pick if you're already on WordPress or your business is content-led (blog, SEO, editorial driving sales).
5. BigCommerce mentioned
   BigCommerce - best when you want depth built in rather than bolted on via apps: native B2B features, multi-currency, and strong handling of large or complex catalogs.
6. Squarespace mentioned
   Squarespace Commerce - for design-led sellers with small, simple catalogs: artists, studios, boutique brands, anyone selling 20 products where the site's look matters more than merchandising logic.
7. Squarespace Commerce mentioned
   Squarespace Commerce - for design-led sellers with small, simple catalogs: artists, studios, boutique brands, anyone selling 20 products where the site's look matters more than merchandising logic.
8. Square mentioned
   Wix eCommerce or Square Online - the beginner tier.
9. Online mentioned
   Wix eCommerce or Square Online - the beginner tier.
10. Square POS mentioned
    Square Online specifically is worth it if you already run Square POS in a physical location, since inventory syncs automatically.
11. Adobe Commerce mentioned
    Adobe Commerce (Magento) - only for enterprise with developers on staff.
12. Shopify Plus mentioned
    Don't go here unless you've outgrown Shopify Plus (which itself starts around $2,300/mo on a 3-year term) or have genuinely unusual requirements.

The answer, as recorded

## Best ecommerce platforms **1. Shopify** - the default recommendation for most people. It powers roughly a third of hosted commerce, and the reason is that everything works out of the box: hosted, fast checkout (their checkout converts noticeably better than most), a huge app ecosystem, and solid multichannel selling (Instagram, TikTok, Amazon, POS). Basic is $39/mo ($29 billed annually). The catch: if you use an external payment gateway instead of Shopify Payments, you pay an extra 2%, and app subscriptions can quietly exceed your plan fee as you grow. **2. WooCommerce** - the pick if you're already on WordPress or your business is content-led (blog, SEO, editorial driving sales). The plugin is free and you own the whole stack with no transaction fees, but "free" is misleading - with hosting, a theme, and the paid extensions most stores actually need, realistic total cost is roughly $1,000-$3,000/year, plus you're the one responsible for updates and security. **3. BigCommerce** - best when you want depth built in rather than bolted on via apps: native B2B features, multi-currency, and strong handling of large or complex catalogs. Entry plan is around $29/mo. Note they renamed plans (Core, Growth, Scale) in June 2026 and added a 2% fee on non-embedded payment gateways, so the old "no transaction fees" pitch is weaker than it used to be. **4. Squarespace Commerce** - for design-led sellers with small, simple catalogs: artists, studios, boutique brands, anyone selling 20 products where the site's look matters more than merchandising logic. Core is $23/mo. It's the prettiest out of the box and the fastest to a site you're not embarrassed by, but it hits a ceiling fast on catalog and fulfillment complexity. **5. Wix eCommerce or Square Online** - the beginner tier. Cheapest entry, fastest launch, minimal decisions. Square Online specifically is worth it if you already run Square POS in a physical location, since inventory syncs automatically. Plan on migrating off eventually if the store takes off. **6. Adobe Commerce (Magento)** - only for enterprise with developers on staff. Total control, complex pricing, real engineering cost. Don't go here unless you've outgrown Shopify Plus (which itself starts around $2,300/mo on a 3-year term) or have genuinely unusual requirements. **Short version:** start on Shopify unless you have a specific reason not to. That reason is usually "I'm on WordPress already" (→ WooCommerce), "my catalog is huge or B2B" (→ BigCommerce), or "I sell 15 things and care about design" (→ Squarespace).
